Sesame Street takes a detour to Chernobyl in this clip from the ultra-creepy kiddie show “Peppermint Park.”

As Ernie the puppet - who seems to have lost all his teeth, has Bell’s palsy and the epidermal sheen of someone who has undergone a recent face transplant - sings about the letter “M,” I can’t help but wonder what kind of horrible deformities are hidden beneath those gloves he’s wearing. Some kind of radiation-related disfigurement? All I know is he’s the saddest fucking puppet I’ve ever seen and I’m torn between sympathy and horror.
